Operation

Preparation

1.Before operation, check the Vacuum Pump oil level. Do this by looking through the opening on the lower right side of the back panel. You will be able to see the vacuum pump oil reservoir. The level must be between the MIN and MAX mark- ings. If the oil level is low, open the back of the machine, remove the cap of the oil reservoir and fill to the MAX line with good quality compressor oil. Replace the oil cap and back of machine before beginning operation. DO NOT OPERATE THIS MACHINE WITHOUT ADEQUATE OIL IN THE VACUUM PUMP, SEVERE DAM- AGE WILL RESULT.

2.WARNING: The A/C (air conditioning) system is under high pressure. Do not loosen any hose fittings or remove any components until after the system has been com- pletely discharged and depressurized. Removal or loosening of a component while the system is under pressure can cause severe personal and property damage or injury.

1.Check the vehicle compressor drive belt. If it is worn or cracked, it should be re- placed before any other service is performed.

2.Check the vehicle system hoses. Look for cracks, bubbles, hard spots and dete- rioration. Inspect all hoses and fittings for leaks and refrigerant seepage. If there is any evidence of wear, replace the damaged parts before performing any other service.

Note: Use of a leak detector kit (not included) is recommended.

3.Inspect the compressor fins for debris that may be impeding heat dispersion of the compressor. Clean between the fins with a tool or compressed air.
